BUF634PG4

Overview

The BUF634PG4 is a high-speed buffer amplifier manufactured by Texas Instruments, belonging to the BUF634 series. It features a single channel with a slew rate of 2 kV/us and a voltage gain of 100 dB. The input bias current is 20 uA, while the input offset voltage is 100 mV. Operating on a power supply ranging from 4.5 V to 36 V, it draws 20 mA of working current. The device supports through-hole installation in a PDIP-8 package and operates within a temperature range of -40 C to +125 C.

Feature Summary

• High-speed buffering capability with significant slew rate performance
• Single-channel operational design for signal isolation
• Wide operating temperature range suitable for industrial environments

Applications

• Video signal buffering
• High-speed data acquisition systems
• Test and measurement equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for end-of-life notifications or obsolescence notices prior to procurement decisions. Ensure packaging specifications match design requirements for through-hole mounting processes.

Selection Notes

Select this component when high-speed signal buffering is required with through-hole mounting constraints. Consider the specific input offset voltage and bias current parameters for precision applications. Evaluate the wide supply voltage range against system power availability. Verify thermal management capabilities given the extended operating temperature limits.

Part Context

This part belongs to the BUF634 family of high-speed buffer amplifiers from Texas Instruments. It shares core functional characteristics with other variants in the series but differs in packaging and specific electrical tolerances. The PG4 suffix typically denotes lead-free and RoHS-compliant construction compared to earlier versions.

Replacement Considerations

Consult official Texas Instruments documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications before substituting. Verify compatibility with existing PCB footprints and thermal requirements.
